A few years back I took a trip to Sapporo over the New Year's holiday. It snowed ~3 inches per day the entire week I was there. I consider myself pretty comfortable with cold weather (I went up there so the girl I knew could teach me to snowboard). I'll be damned if I ever agree to give up a private auto in favor of biking in that sort of weather. I didn't even like her FWD Kei car, and wished I was in an AWD Lancer Evolution or Subaru WRX instead.
